本的な解決策が望まれていた。 A push button switch is used in keyboards of small electronic computers, etc., which is an example of an operation display, and is made of a dome-shaped push button switch made of rubber elastic material with a contact member attached to the center of the back surface. Generally, numbers and codes such as calculation signals are printed on the top of the key top to indicate the role of the key. This code is printed by applying ink to the key top surface. However, in this type of conventional printing, printing is difficult if the key top surface of the push button switch is not flat. Furthermore, since the code is printed in an embossed manner on the key top surface, the printed code is likely to peel off and the appearance of the pushbutton switch is impaired. Furthermore, silicone rubber, which has excellent durability, heat resistance, cold resistance, etc., has good colorability, and has characteristics such as less change in properties such as height and elasticity due to temperature changes, is used as a material for the rubber push button switch. However, when a rubber push button switch is made of silicone rubber, printing is difficult because printing ink does not adhere well to the switch due to the non-adhesive nature of silicone rubber. Furthermore, since printing is performed on vulcanized silicone rubber, the printed undried ink tends to bleed into the surrounding area, making it difficult to maintain extremely fine lines. Therefore, a drastic solution has been desired for printing on an operation display body whose main body is made of silicone rubber.

る。 In FIG. 1, which is a sectional view showing the configuration of a mold for manufacturing a push button switch, reference number 1 is shown.
is a mold, which includes an upper mold 2, a middle mold 3 that functions as a female mold, a lower mold 4 that functions as a male mold, and an upper mold 2.
and a transfer plate 5 inserted between the medium mold 3.
2', 3', 4', and 5' are guide holes provided on both sides of the upper mold 2, middle mold 3, lower mold 4, and transfer plate 5, respectively, so that they overlap each other. It is provided. 6 is a guide pin, and the upper mold 2, middle mold 3, lower mold 4, and transfer plate 5 are stacked as shown in the figure by fitting the guide holes 2', 3', 4', and 5' into this guide pin 6. It will be done. Further, as shown in the figure, the middle mold 3 and the lower mold 4 have molds formed by recesses 7 and protrusions 8 for mutually molding the switch body. As shown in the figure, when the middle mold 3 and the lower mold 4 are stacked, the convex portion 8 faces the concave portion 7. Further, a portion of the transfer plate 5 held between the upper mold 2 and the middle mold 3 covers the upper part of the recess 7 of the middle mold 3, and is given the role of smoothing the upper surface of the switch body.
That is, the transfer plate 5 is made of a rigid body rather than a flexible synthetic resin or the like, and serves to smoothly form the upper surface of the key top during heat forming.

４図に示すプレス機械により加熱及び加圧する。 First, as shown in FIG. 2, a code 9 is printed embedded in a push button switch at a predetermined portion 5a of the transfer plate 5 exposed inside the mold from the recess 7 of the medium mold 3.
is applied in advance by screen printing with printing ink. Therefore, the attached code 9 is the transfer plate 5.
It stands out (protrudes) from above by the thickness of the wall.
In this case, the printing ink used is a mixture of a polyxyloxane polymer and a pigment for coloring. The transfer plate 5 on which the reference numeral 9 has been printed in advance as described above is held between the upper mold 2 and the middle mold 3 by overlapping them (FIG. 3), and this state is fixed by appropriate means. Next, silicone rubber 10 of a predetermined size, which will become the pigment of the push button switch, is placed on the convex portion 8 of the lower mold 4, and the upper mold 2, transfer plate 5, and middle mold 3
are overlapped and fixed together, and then passed through the guide pin 6 and overlapped. Further, the superimposed molds 1 are heated and pressurized using a press machine shown in FIG.

2 is a guide post, 13 is a heating plate fixed to the upper part of the guide post 12, 14 is a heating plate movably attached below the guide post 12, and 15 is a pressure machine that moves the heating plate 14 up and down. If the mold 1 is mounted on the hot platen 14 of the press machine 11 as shown in the figure, and the hot platen 14 is raised by the pressure machine 15, the mold 1 is pressurized by the hot platen 13 and the hot platen 14. Heating takes place.

るので転写板５からはぎ取られる（第６図）。 By pressurizing and heating the mold 1 as described above, the silicone rubber 10 is molded into the medium mold 3 as shown in FIG.
It is then molded into a rubber push button switch using pressure and heat in the lower mold 4. At the same time, the reference numeral 9 printed on the transfer plate 5 has a vulcanization mechanism similar to that of the silicone rubber 10, so it is embedded in the silicone rubber 10 as shown and is vulcanized integrally with the silicone rubber that forms the body of the switch. For this reason, the reference numeral 9 forming the printing layer and the silicone rubber 10 are integrated. Therefore,
After vulcanization, remove the mold 1 and peel off the transfer plate 5. Since the code 9 embedded in the key top surface of the push button switch 16 is vulcanized together with the silicone rubber 10, it can be peeled off from the transfer plate 5. (Figure 6).

ある。 As explained above, according to the present invention, a code made of polysiloxane is embedded in the display surface of an operation display body having a similar vulcanization mechanism, and then both are vulcanized and integrated. In other words, the method of the present invention does not simply involve pressure bonding, but involves vulcanization, a so-called crosslinking reaction in which the surface of the substrate and the ink form a three-dimensional network structure through heat and pressure, thereby completely bonding the surface of the substrate and the ink. occurs and is printed in combination.
Therefore, the code printed on the transfer plate is combined and transferred to an operation display such as a key top. Therefore, it is possible to provide an excellent product and its manufacturing method in which the appearance of the operation display body is not impaired and the code does not peel off at all. Furthermore, the symbols can be attached regardless of the shape of the display surface. Further, since the symbols can be attached at the same time as the operation display body is formed, it is efficient and the operation is extremely easy.
